All of the sense organs are both organs and capacity. The synthesizing acting of the heart continuously creates a unity of the inner world and outer world. Moments in which we perceive this unity are moments of the experience of beauty. Beauty is thus a consciousness of the heart. The heart has always been connected with love due to this relation between bringing what seems to be separated into conjoining as profound beauty.
Some time ago, I was at a concert and listening to the orchestra beginning to tune up. It was the most discordant sound I've ever heard. Each instrument was playing in its own way, in total disharmony. Then the oboe, a quiet little instrument, began to play and all the other instruments turned in on its note. And gradually, all the disharmony began to calm down. Then there was silence, and the concert began. It seems to me that the mantra is very much like that little oboe. In meditation, the mantra brings all the parts of our being, one by one, bit by bit, into harmony. And when we are in harmony, we are the music of God.
